What the work involves

Employers must make sure every enclosed workplace is ventilated by a sufficient quantity of fresh or purified air under the Workplace (Health, Safety and Welfare) Regulations 1992. In practice, designers work to rates such as 10 litres a second per person for offices, taken from Approved Document F and CIBSE guidance, and adjust for meeting rooms, kitchens and toilets. Typical jobs are fit-outs and refurbishments: a new tenant needs ventilation to match a new layout, an old system cannot keep up with more staff, or a change of use needs a fresh design.

Demand control

CO2 or occupancy sensors that slow the system when rooms are empty.

Design and build or install-only

We design it, or install to a consultant's drawings.

Heat recovery supply and extract

One or more units with ductwork to diffusers, sized for occupancy.

Questions about commercial ventilation design and installation in Kent

Which rules apply to ventilation in Kent?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.

Do we need building regulations approval?

New or altered ventilation in non-domestic buildings usually forms part of the building control application for the works. We provide the design information and commissioning records needed.

Can the system cool as well?

Ventilation alone moves air; it does not cool much. Where cooling is needed we can coordinate with the air conditioning installer.
